SHUTTLE-CHAN GING LOOM.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Aplication filed June 18, 1908. Serial No. 439,141.

To all whom it may concern:

lie it known that l, Bnxamux F. Mo- (ii'ixnss, a citizen of the United States, residing at Worcester, in the county of Worccs ter and State of Massachusetts, have invented certain new and useful Improvements in Hhnttle-Cltaoging Looms, of which the following is a specification.

My invention relates to shuttle changing looms, and particularly to a shuttle changing mechanism for looms which have an ordina1' single box at each end of the lay, and by means of which mechanism, preferably operated by the weaver, a shuttle having a full supply of filling may be exchanged for a shuttle having the filling substantially or practically exhausted, whenever the weaver desires. Instead of having the mechanism operated by the weaver, 1 may provide, in connection with my improvements, a pattern surface, which at certain intervals, at a predetermined time. through intermediate connections, will automatically operate the shuttle changing mechanism. For instance, when the loom is weaving a coarse fabric, and the filling is preferably of a coarse character, there is less filling on the bobbin, and the exhaustion of the bobbin will take place in a comparatively short time, and as the weaver knows the amount of filling on the bobbin, a continuously running pattern chain may be made, which will indicate the change of the shuttle after a certain number of picks and when the bobbin in the running shuttle is nearly exhausted, and will, through intermediate connections, put into operation my mechanism, by means of which a new shuttle with a fresh supply of filling will be automatically substituted for the running shuttle having the filling substantially exhausted, without stopping the loom, or losing a pick.

in applying my improvements to a loom, I combine with the single shuttle box, preferably on the right hand end of the loom, a drop box, and switch box mechanism, which may be of the same construction and operation as shown and described in my pending application, Serial No. 350,336. In this iiistanec I provide one box for the running shuttle, and the box for the spare shuttle has its upper part provided with a movable plate, to receive the shuttle to be exchanged, and then leave the lower part free for the spare shuttle to be picked out. of its box.

I have only shown in the drawings a detached portion of a loom of the class referred to. with my shuttle changing mechanism combined therewith, sutlicient to enable those skilled in the art to understand the construction and operation of the same.

Referring to the drawings z-Figure 1 is a front view of a loom having a single box, and a single box on the right hand end, and. a drop and switch box mechanism, and my mechanism for operating the same, on the rightv hand end. Fig. 2 shows a detached portion of the mechanism shown in Fig. 1, at the lower right hand part. Fig. 3 the mutilated gear mechanism shown at the left in Fig. 2, detached. and shown as a section, on line 3, 3, Fig. 9, looking in the direction of arrow 0, same figure. Fig. 4 is a section on line l, i, Fig. 1, looking in the direction of arrow 7), same figure; the broken lines show the spare shuttle boxes in their inoperative position. Fig. 5 corresponds to Fig. l, but shows the boxes in their lower position, when the shuttle is to be exchanged. Fig. 6 is a front view of the spare shuttle boxes, looking in the direction of arrow 0, Fig. 4. Fig. 7 is a plan view of the parts shown in Fig. (3, looking in the direction of arrow (Z, same figure. Fig. 8 corresponds to Fig. 6, but shows the spare shuttlc boxes in their lowered position when a shuttle is to be exchanged, and looking in the direction of arrow c, Fig. 5. Fig. 9 is a section, on line 9, 9, Fig. 2, looking in the direction of arrow f, same figure. Fig. 10 is a section, on line 10, 10. Fig. 2, looking in the direction of arrow g, same figure. Fig. 11 is a plan view of the parts shown in Fig. 10, looking in the direction of arrow h, same figure. Fig. 12 shows the parts shown in Fig. 11, in a different position.

In the accompanying drawings, 1 are the loom sides, 2' is the breast beam, 3 the arch, l the lay sword at the left hand end of the loom, 5 is a stationary shuttle box of ordinary construction, at the left hand end of the lay (3, 7 is the picker stick; l is the lay sword at the right hand end of the lay (3. S is the shuttle box guide plate, secured to the. upper end of the lay sword at the right hand end of the lay G.

A shuttle box 9, of ordinary construction, to receive the shuttle when the loom is running normally, is supported on the upper end of the shuttle box lifter rod 10. The

lower end of the lifter rod 10 is connected with the roeker iron 11, in the usttal way. A. helieally coiled contraction spring 1:2 is mounted on the lifter rod 10. The lifter rod it! is connected at its lower end with one end of a tlexihle connection 1 which passes over sheaves 1t and 1.3, in the ordinary way. and leads to the hox motion lever, to be hereinal'ter described.

cell 10 f r the spare shuttle l7, and a cell tor the shuttle to be exchanged, are in this instance supported upon an upright swinging hand lever 11]. which is pivotally connected at its lower end to the box lifter rod it). to move therewith. The cell it) is to receive the spare shuttle 1T. placed therein. by the weaver. and the upper cell 18, which in this instant-e has a part of the shuttle shell ts thereof pivotally mounted on a. stud it to have a tilting motion thereon, is to reeeiuthe shuttle to be exchanged. The longer end of said tilting shelf extends inwardly. so that the weight thereof will hold the shell in an inclined position, as shown. in Fig. U, with the inner end thereof in line with the race-way ot' the lay, as shown in Fig. 5. when the shuttle boxes at. the right hand end of the loom are lowered. so that the shuttle to lie ext-hanged will pass up said inclined plate 18'. which acts as a switch plate. and tilt said switch plate into a horizontal po ition. as shown l; v broken lines in Fig. leaving the spare shuttle 1? tree to be picked from the spare shuttle box It The upright hand lever 10 is suhstantially ot' the saute construction and operation as the upright hand lever shown and described in my pending application, Serial No. 350.336. alioie referred to. It is connected to the shuttle l)()X .l. and locked in position, to he raised and lowered with said shuttle box, and is disconnected and moved out-- wardly, as shown by broken lines in Fig. 4-, for the purpose of removing the shuttle ha v-- ing the exhausted filling. and to supply a new shuttle.

I will now describe the box motion shown in the drawings, for raising and lowering the shuttle boxes at the right hand end of the loom. for the normally running shuttle, and for the spare shuttle, and for the shuttle to be exchanged. Fast on the bottom sha'lt: 2t! of the loom is in this instance a n'mtilated, or what is termed a master gear 21. which meshes with and drives a. mutilated pinion 22. mounted on a sleeve 23', and connected therewith in this instance by a spline 23". to have a sliding motion in the direction of the length of said sleeve. and to rotate with said sleeve. The sleeve 23 is loosely mounted on a stud 12%. secured in a hanger or bracket 25 on a stand it? on a girt 27 extending between the ends of the loom. ()n the sleeve 23 is a crank disk 23. see Fig. 9.

A half revolution of the mutilated pinion 22 and of the crank disk 23 is communicated from the master gear 21. when the respective tooth portions of the mutilated pinion 2; aml the master gear .21 are moved into en gagement with each other.

The mutilated pinion 22 is moved longitudinally on the sleeve 23. through the vokeshaped lever 28, pivotally mounted at the lower end of the hanger 2.3 amt engaging with an annular groove '1'! in the huh 22" of the mutilated pinion 2;.

A crank pin 23' on the crank disk 2 extends iuto and travels in an elongated slot 29' in one end of the box motion lever in. which is pivotally mounted on a stud ill) on a stand 31 secured to the cross girl .37. The other end of the hex motion lever is eonneeted with the lower end of a rod 13'. forming a part. ot the tlexihle connection .13 to the box lifter rod 10, see Fig. l.

The crank disk has on its periphery. in this instance two recesses or depressions 23. on opposite sides of its axis. Fig. J, and a roll 33 on an arm 34- is adapted to extend into one of said recesses. in the revolution oi" the crank disk 23. to hold or lot-k said disk in its two oppvsite positions. A helieally coiled contraction spring 33 is attached at one end to said arm 34-. and at its other end to a stud 3h on the girt 212; said spring 2}, acts to yieldingly hold the roll 13; on the arm Ill in engagement with the periphery of the disk To move the mutilated pinion 2; into and out of mesh with the master gear 21. I provide mechanism operated hy the weaver at the desired time. or antomatieally operated by a pattern surface.

I will first describe the mechanism oper ated by the weaver. The lower end of the lever 28 is connected by a rod or eonneetor 37 with one arm of an angle lever 38. which has its hub 38' loosely mounted on a stud 33 on the lower end of a bracket. or support 40 seemed to the loom side. see Figs. 3, and ltt. The other arm of the angle lever 38 is ton nected to the lower end of a rod or eonneetor -l1. which rod extends through a recess if in an arm 12. whieh has a yoke-shaped end 12" pivotallv connected by a pin 42' with an extension 4-1 on the hub at" of a hand lever 44. which has its hub 41" pivotally mounted on a stud at?) on a stand to secured to the loom side, see Fig. 10.

The hand lever 4-1 has a handle it. preterably at the front of the loom. atnl a projeetion 44 on the underside of the lever it is adapted to extend into either one of two V shaped recesses 47 in a stand 47 secured to the loom side. see Fig. 2. to hold said hand lever in its two positions. projection ll on the hand lever 4-1. Fig. 10. limits the downward movement of the arm 4;. eollar -18, adjustably secured on the upright rod 41 by a set screw 49, extends over the arm Cit 42. cam is fast on the bottom shall it], see Fig. it), and when the hand lever it is moved into its operative po ition, to carry the arm ii in the path of the periphery of the cam fit]. as shown in Fig. l], the revolu tion of said cam will raise the arm 42, from the position shown by broken lines in Fig. it). to the position shown by full lines in said figure. and through the engagement of said arm 42 with the collar 48 on the rod l1, will rock the angle lever 38, and through the connector 37 move the lever to slide the mutilated gear :32 on the sleeve 23' into the path of the teeth on the master gear 21, to cause a partial rotation of said sleeve and the crank disk :23, and the movement of the box lever it), and of the shuttle boxes 9, 1t), and 18.

(in the arm 4" is secured. by a set screw 51, a boss :32 on the upper end of a downwardly extending finger 52. see Fig. 10. and in the continued revolution of the cam 50 on the bottom shaft 20, the side cam portion 50' on the cam 50 will engage said finger 52,and move the arm 42 back to its inoperative position. shown in Fig. 12. atter the shuttles have been exchanged and the extra shuttle boxes have been raised to their normal position. and also lever H.

The lower end of a Hat spring blade 53 is secured to the rocker iron it. see Fig. l, the upper end of said spring 53 engages a stud or bolt 19 011 the upright lever 19, and acts to move back the upright lever 19. and the shuttle boxes carried thereon, to their inoperative position, shown by broken lines in Fig. 4.

In case it is desired to operate the boxes auton'iatically through a pattern surface, a pattern cylinder 54, suitably mounted on a stud 55, see Fig. 1, may be used, carrying any ordinary pattern surface. and adapted to operate a pattern indicator lever 56. The pattern indicator lever 56 is connected to the upper end of the rod 41, and the movement of said indicator lever 56 will move said rod ll, and through lllttlll'l'ledlttte connections to the lever 28, will operate the mutilated pinion 22, to put into operation the shuttle box motion. The pattern chain may be so constructed that at predetermined intervals and after a certain number of picks, the shuttle box motion will be operated to bring the cell. to receive the exhausted shuttle in line with the race-way, and then to bring the shuttle having the spare cell there in in line with the race-way, to have said Shuttle picked.

It. will be understood that the details of construction of my improvements may be varied if desired, and they may be adapted to he applied to different types of looms.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
